• dynamics of meteoroids and dust; effects on planetary environments
• dynamical evolution of planetary satellites
• measuring the solar system through time-critical phenomena (eclipses, appulses, occultations, transits)

My research has featured prominently in the media. During the 2015 DPS Meeting (Washington DC) I participated in a press conference (http://aas.org/media-press/archived-aas-press-conference-webcasts) and contributed a press release (https://www.nasa.gov/feature/goddard/mercury-gets-meteoroid-shower-from-comet-encke) to promote my result that the meteoroid stream of comet Encke is responsible for modulating Mercury's calcium exosphere.

My earlier discovery of a cluster of Trojans at the orbit of Mars was similarly publicised during the 2013 DPS (Denver, CO; press release at http://spaceref.com/asteroids/an-asteroid-pile-up-in-the-orbit-of-mars.html). In 2011, I identified 2010 SO16 as a long-lived Earth horseshoe asteroid (still the longest-lived Earth coorbital at the time of writing this) and a press release was issued by the UK's Royal Astronomical Society. On all these occasions, the stories were reproduced on numerous fora across the world wide web. I am also involved in a proposal with Craig Agnor and Carl Murray (QMUL) to bring a DDA meeting to London in 2017 or later.

Services, Roles, and Activities

I am a Fellow of the UK Royal Astronomical Society, a full Member of the American Astronomical Society (DPS & DDA), also a Member of the American Institute of Aeronautics and Astronautics and of the International Astronomical Union Commission 7: Celestial Mechanics and Dynamical Astronomy.

I regularly act as reviewer for papers submitted to Science, Icarus, Astronomy & Astrophysics, Celestial Mechanics and Dynamical Astronomy, Monthly Notices of the Royal Astronomical Society, Journal of Geophysical Research, Geophysical Research Letters and others. In 2014, I was awarded a "Certificate of Excellence in Reviewing" by the Editorial Board of Icarus. I have also reviewed grant proposals in the UK and internationally, including a number of Solar System Workings programme applications in 2014. During the 2013 European Planetary Science Congress in London, UK, I organised and chaired the "Asteroid Dynamics" session. I have written press releases issued by the Armagh Observatory and occasionally by other organisations (eg Division of Planetary Sciences of the AAS, Royal Astronomical Society in the UK). I also give talks to amateur societies and organise public observing sessions using the Observatory's historical Grubb 10-inch refractor.

Professional Experience and Positions

• 03/2001 - present: Research Astronomer, Armagh Observatory, UK
• 03/2000 - 03/2001: Research Associate, Orbit & Attitude Determination & Control of Small Satellites, University Surrey, UK
• 10/1998 - 03/2000: Research Associate, Theoretical Astronomy, Astronomy Unit, Queen Mary University of London, UK

Candidate Statement

None of us would be working in this field if we were not convinced of the importance of dynamics in answering the fundamental science questions in astronomy. As a planetary scientist and a DDA member for over 15 years, I have been impressed - but never surprised - by its enormous contribution to understanding our own solar system, my main area of research.

But I feel that dynamics can make a still bigger impact (read "more projects and more job opportunities for dynamicists") if we bolster our lines of communication to the other disciplines. A recent personal experience has been the Mercury-related item I describe under the "Research Area" section above. That story began in 2009 during a workshop I helped organise in Graz, Austria under a European Union grant that brought together experts in planetary exospheres and cometary dust dynamics. The result was - apart from a nice paper in GRL(!) - that we now know something we didn't, namely that meteoroid streams can affect exospheres in a measurable way. If elected, I will work to foster and promote cross-discipline linkages and actions to help our field and its practitioners realise their full potential.

Candidate Statement

Candidate Statement: I always look forward to the DDA meeting each year because of the variety of interesting dynamical problems explored and the fact that the small meeting size allows plenty of time for discussion (and no parallel sessions!). If elected, I would focus on maintaining the high quality of the DDA meetings by making sure they remain affordable to attend and by encouraging early career researchers to join the DDA.

Candidate Statement

The DDA is a smaller community than most other AAS divisions. This is partly what makes DDA great, as meetings are much more interactive. But this also demands greater care and attention in order to maintain DDA’s research excellence and diversity. To this end, I would work to reinvigorate DDA’s galactic dynamics component and try to find ways to generate cross-discipline discussions at meetings. DDA is small enough that such efforts could be effectively organized. I would also work to attract outstanding young researchers to DDA and to continue improving the division’s gender balance.

Professional Experience and Positions

Candidate Statement

The DDA meeting is smaller and more relaxed than most conferences. The friendly atmosphere is great, but sometimes the DDA feels like a well-kept secret. I’d like to explore all avenues to make sure that potentially interested scientists know about the meeting and feel welcome if they attend. Although exciting discoveries on extrasolar planets have been a welcome new topic of discussion at recent DDA meetings, the meeting’s focus has, overall, narrowed in recent years. Our bylaws state that we seek to advance all aspects of dynamical astronomy, including stellar and galactic dynamics and the dynamics of the interstellar medium, but these topics have been little discussed of late. We need to foster cross-disciplinary research, so I welcome the topical sessions on astrometry and disk/ring systems planned for the 2016 meeting. I support the DDA’s initiative to select the Brouwer Award winner in a more inclusive way. Finally, I would like the DDA to explore new forms of outreach, such as publicizing new results in dynamics on social media and recording talks at our meetings so they can be viewed on the web.
